Question
A police car moving at
, changes a motorcyclist. The police man sounds his horn at 176 Hz, while both of them move towards a stationary siren of frequency 165 Hz. Calculate the speed of the motorcycle, if it is given that he does not observe any beats.
-
- Zero
The correct answer is:
The motorcyclist observes no beats. So the apparent frequency observed by him from the two sources must be equal.
Solving this equation we get,
